[1.19.2] Shapes net.minecraft.world.phys.shapes.BooleanOp.class, make cubic shape whit a hole inside

[perromercenary00]

hi good nights 
im doing a custome toilet block and i need to set the collition boxes for it in four direction but for the explanatory process i only talking about facing nort 

i have two main collition boxes
one for the chair and one for the tank 

    protected static final VoxelShape NB_0 = Block.box( 3.0D, 0.0D, 4.0D, 10.0D, 8.0D, 12.0D); //base chair
    protected static final VoxelShape NT_0 = Block.box( 1.0D, 7.0D, 0.0D, 14.0D, 9.0D, 4.0D); //water tank
	

i need the base chair part to have a hole in the center

soo i made the hole a shape   hopping to find a way to just sustract the hole area form the base box and later just joint the tank part 

 

	like 
	
	 
	    protected static final VoxelShape HOLE = Block.box( 6.0D, 0.0D, 6.0D, 10.0D, 8.0D, 10.0D);
   //base whit a hole =>  Shapes.join( NB_0, HOLE, BooleanOp.? )
	    
    protected static final VoxelShape caja_n = Shapes.join( Shapes.join( NB_0, HOLE, BooleanOp.? )  ,NT_0 , BooleanOp.OR);
                                               //Shapes.join(caja, Y_5_AABB, BooleanOp.OR);

 

soo iwas looking inside the BooleanOp.class

net.minecraft.world.phys.shapes.BooleanOp.class

an don't get a thing 
i guest is coze im not a english speaker soo this things dont make sense for me 
is like here im joining too forms using BooleanOp.OR   but that dont make sense, 
in mi languague  that must be a BooleanOp.AND operation 

soo how i cut the small hole shape from the  bigger base chair part ? 

 

thanks for you time

Look at what the AbstractCauldron or HopperBlock does. Or in general:

Shapes.join(original, cutout, ONLY_FIRST);

i.e. start with "original" and only takes the parts that are in that shape but not in "cutout".

ya thanks that makes the tric works 

				
			    protected static final VoxelShape HOLE = Block.box(6.0D, 0.0D, 6.0D, 10.0D, 8.0D, 10.0D);				
			    protected static final VoxelShape caja_n = Shapes.join(Shapes.join(NB_0, HOLE, BooleanOp.ONLY_FIRST), NT_0,
		            BooleanOp.OR);				
			

i have curiosity is somewhere explained how to use the other options, 

some of it just breaks the code and makes minecraft fails saying mi toilet block is null
